I was hoping some long-toothed experts would chime in before naysayers so, just to set the record straight, no, many service functions can easily be done elsewhere and Tesla sort of encourages it.
Tires, alignment, brakes, glass repair (to an extent - roof glass replacement might be hard to find elsewhere), and some suspension work. Plus, they give guidance on a few DIY things like cabin air filter, wiper blades, etc. I’m sure there’s other stuff but, suffice to say, if it isn’t HV related and, especially if you’re no longer under warranty, treat it like any other car and DIY or have it worked on wherever you feel safe doing so.
As for windshield replacement, you shouldn’t need to go to Tesla but they’ll certainly do it right. Safelite and others will try to charge you for camera calibration but the car will do it on its own unless they broke something or really knocked a camera out of position. If I recall correctly, it should be done well under 40 miles of driving provided there were sufficient road markings for the cameras to orientate. If you’re not even seeing some indication that it’s in progress, other than setting up an appointment with Tesla, the only suggestion I have is to do a reboot and restart the calibration again. If you do go to Tesla, I would personally argue that Safelite should be responsible for any repairs caused by their mistakes. You can always check their contract language and/or (try to) get them to admit in writing that they can’t figure it out so you need to go to the manufacturer.
Don’t know anything about a humidity sensor but I’m not tuned in to that level of maintenance knowledge on these cars.
